//传送参数:
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="++"’)</script>")
//接收参数:
string a = Request.QueryString("id");
string b = Request.QueryString("id1");

Button1.Attributes.Add("onclick","return confirm(’确认?’)");
button.attributes.add("onclick","if(confirm(’are you sure?’)){return true;}else{return false;}")
